What does an asterisk do in a CSS property name?

I’m going through css style sheet provided with twitter bootstrap 2.0 and I see a lot of properties for which a * is appended before them. Ex: *margin-top , *zoom, *display etc..

What does this * imply ? Ex: listing of one of the rules –

audio, canvas, video {
  display: inline-block;
  *display: inline;
  *zoom: 1;
}

The *<property> is used to target IE7 (and below).
